Siemens 6ES7 322-1HH01-0AA0 Simatic S7 Output Module

Siemens 6ES7 322-1HH01-0AA0 SIMATIC S7 Output Module is a 16-channel digital output module (SM322) for the SIMATIC S7-300 family, delivering isolated relay contacts for discrete control. It provides 16 DO channels with a 1x 20-pole interface for backplane mounting, enabling compact expansion of I/O in a rack-based automation setup. Each output is a relay contact capable of switching loads at 24 V DC or at AC voltages (120 V or 230 V) up to 2 A per channel, making it suitable for energizing actuators, indicators, or relays in industrial control applications. Designed for use in S7-300 configurations, this module supports straightforward integration with Siemens engineering environments for diagnostics and wiring.
